NAUTlCAL SIGNAL.

Specification of Letters Patent.

Patented May '7, 1907.

Application filed February 5, l 9 06. Serial No. 29 9, 6 5 '7.

To @ZZ whom t may concern:

Be it known that I, FREDERICK O. BER- wroK, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Nautical Signals; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to nautical signals and it consists ofl a novel arrangement of devices whereby an alarm may be sounded and a light flashed simultaneously.

One of the principal objects of the invention is to provide a simple and effective means of warning approaching or passing vessels of possible danger at night or during foggy weather.

Other objects of the invention will be readily apparent upon a complete disclosure thereof.

In the drawing-Figure 1 is a side elevation of my improved signal. Fig. 2 a vertical central section of the lamp. Fig. 3 a top plan of the devices for shielding the light; and Figs. 4 and 5 detail views, showing the arrangement of the operating mechanism.

Referring to the several views, the numeral 1 indicates the sound-producing device, which, in the present instance, is a whistle of the ordinary type, and 2 the lamp. The whistle is mounted upon the upper end of a steam or air pipe 3, connected with any suitable source of supply, and secured to the valve 4 of said whistle is a spring-controlled lever 5, by means of which the steam or air maybe allowed to escape through the whistle.

Secured upon the pipe 3 are brackets 6, 6, in which is supported the lamp 2. The lamp may be of `any approved shape, preferably cylindrical, and is provided with a bottom plate 7 and a top plate 8, each being provided with suitable air openings. The lamp casing is provided with a storm glass 9, through which the light may be refiected when desired.

In carrying out my invention, I prefer to use acetylene gas oroil as a light-giving flame, and to alternately conceal and iiash the light I prefer toemploy a pair of oppositely operating shields or shuttles 10, 10, al-

though it will be understood that I may employ any device that can be operated to alternately conceal and flash the light.

Each shield is secured to a bottom segment 11, and to an upper segment 12, by rivets 13, as shown in Fig. 2. The bottom segments are pivoted, one upon the other, on a central boss 14 on the upper face of the bottom plate 7, and are held against accidental displacement by a nut 15. The lower or under face of the bottom plate is also provided with a central boss 16, and an aperture is provided for the passage of a gas-pipe 17.

The upper segments are pivoted on a boss 18 on the under side of the top plate 8, and are held against accidental displacement by a washer 19 and a screw 20. Both the lower and upper segments are provided with suitable air passages. The shields or shutters are operated by a three-arm lever 21, mov-l ably attached to the upper face of the top plate by a screw 22 passing through a longitudinal slot 23 in said. lever. The oppositely disposed arms of the lever are each provided with a longitudinal slot 24, at right angles to the slot 23, through which projects a pin 25, secured to the upper segment, the top plate being provided with a curved slot 26 for each pin. The free end of the third arm of the lever 21 is connected to one arm of a bellcrank lever 27, which is pivoted within an opening 28 of the upper bracket 6. The other arm of the bell-crank lever is connected, by a cord 29, with the free end of the lever controlling the whistle valve, and an operating cord 30 is attached to the other end of said arm.

The valve of the whistle and the shields or shutters being normally closed, a pull on the cord 3() will cause the horizontal arm of the bell-crank lever to move downward, opening the whistle valve to the escape of the air or steam, and the vertical arm of said bellcrank lever to move Outward, moving the lever 21 in the same direction and thereby forcing the shields or shutters to move on their pivots in opposite directions, flashing the light simultaneously with the sounding of the whistle.

Various modiiications or changes in the details of construction of my invention may be made without limiting the scope thereof.

Having thus fully described my invention IOC 2o lever and connections adapted to operate what I claim and desire to secure by Letters l- Patent, is-

l. In a nautical signal, the combination of asound-producing device, a signal light, a normally closed valve, a spring-controlled lever normally holding the sound-producing device inoperative, a pair of shields or shutters concealing the signal light, means adapted to alternately open and close the shields, and connections 'between the spring-controlled lever and the means for opening and closing the shields, whereby an alarm may be sounded and a light ilashed.

2. In a nautical signal, the combination of a sound-producing device, a si'gnal light, a normally closed valve, a spring-controlled lever normally holding the sound-produ ing device inoperative, a pair of shields or shutters concealing the signal light, a three-arm the shields, anda connection between the spring-controlled lever and the three-arm lever, whereby an alarm may be sounded and a light flashed.

3. Ina nautical signal, the combination of a whistle, a signal light', a normally closed valve, a spring-controlled lever normally holding the whistle inoperative, a pair of shields or Vshutters concealing the signal light, a three-arm lever and connections arranged to operate the shields, and a bellcrank lever having one arm attached to the spring-controlled lever and the other arm to the three-arm lever.

In testimony whereo'lI I affix my signature, in the presence of two witnesses.

FREDERICK C. BERWICK.
